There are two main ways to do balancing in the system, cashier balancing and terminal balancing.
Cashier balancing is meant for grocery stores where a cashier might move between several different registers. For example, Jackie might start out the day working on register one, then go on break, come back and finish her shift on register 4. In this circumstance, the cashier would simply move her til from register 1 to register 4 when she switches registers. The money will follow her around and she will be responsible for her own til at the end of the day. When doing cashier balancing, cashiers should not work on each other's tills. If there are any problems with a cashier's drawer, it will be entirely tied to that one cashier.
Terminal balancing is intended for smaller stores with fewer cash registers. In this situation, multiple cashiers will work on the same register. When a cashier leaves the register, they should log off. The next cashier comes up and logs into the register and begins working on the same til. At the end of the day, you will count down the entire register 1 tills which will contain money from all cashiers that rang on that register for the day. The downside of this method is that if there are mistakes, it may be difficult to nail down which cashier made the mistake. Each individual transaction is linked to a specific cashier, and you can view each transaction in the journal, but if there's a problem it could potentially be any of the cashiers that rang on that register's fault.
